swr: Handle resource across context changes

Swr caches fb contents in tiles.  Those tiles are stored on a per-context
basis.

When switching contexts that share resources we need to make sure that
the tiles of the old context are being stored and the tiles of the new
context are being invalidated (marked as invalid, hence contents need
to be reloaded).

The context does not get any dirty bits to identify this case.  This has
to be, then, coordinated by the resources that are being shared between
the contexts.

Add a "curr_pipe" hook in swr_resource that will allow us to identify a
MakeCurrent of the above form during swr_update_derived().  At that time,
we invalidate the tiles of the new context.  The old context, will need to
have already store its tiles by that time, which happens during glFlush().
glFlush() is being called at the beginning of MakeCurrent.

So, the sequence of operations is:
- At the beginning of glXMakeCurrent(), glFlush() will store the tiles
  of all bound surfaces of the old context.
- After the store, a fence will guarantee that the all tile store make
  it to the surface
- During swr_update_derived(), when we validate the new context, we check
  all resources to see what changed, and if so, we invalidate the
  current tiles.

Atomic operation sources are scalar values, but we were failing to

   atomicCounterCompSwapARB(counter, 5u, 10u)

   mov(8) vgrf9.y:UD, vgrf5.xyzw:D

which wrongly selects the .y component of vgrf5, so the actual 10u value
would get dead code eliminated.  The swizzle works for the other source,

vulkan: enum generator: generate extension number defines

New extensions can introduce additional enums. Most of the new enums
will have disjoint numbers from the initial enums. For example new
formats introduced by VK_IMG_format_pvrtc :

VK_FORMAT_ASTC_10x8_UNORM_BLOCK = 177,
VK_FORMAT_ASTC_10x8_SRGB_BLOCK = 178,
VK_FORMAT_ASTC_10x10_UNORM_BLOCK = 179,
VK_FORMAT_ASTC_10x10_SRGB_BLOCK = 180,
VK_FORMAT_ASTC_12x10_UNORM_BLOCK = 181,
VK_FORMAT_ASTC_12x10_SRGB_BLOCK = 182,
VK_FORMAT_ASTC_12x12_UNORM_BLOCK = 183,
VK_FORMAT_ASTC_12x12_SRGB_BLOCK = 184,
VK_FORMAT_PVRTC1_2BPP_UNORM_BLOCK_IMG = 1000054000,
VK_FORMAT_PVRTC1_4BPP_UNORM_BLOCK_IMG = 1000054001,
VK_FORMAT_PVRTC2_2BPP_UNORM_BLOCK_IMG = 1000054002,
VK_FORMAT_PVRTC2_4BPP_UNORM_BLOCK_IMG = 1000054003,
VK_FORMAT_PVRTC1_2BPP_SRGB_BLOCK_IMG = 1000054004,
VK_FORMAT_PVRTC1_4BPP_SRGB_BLOCK_IMG = 1000054005,
VK_FORMAT_PVRTC2_2BPP_SRGB_BLOCK_IMG = 1000054006,
VK_FORMAT_PVRTC2_4BPP_SRGB_BLOCK_IMG = 1000054007,

It's obvious we can't have a single table for handling those anymore.

Fortunately the enum values actually contain the number of the
extension that introduced the new enums. So we can build an
indirection table off the extension number and then index by
subtracting the first enum of the the format enum value.

This change makes the extension number available in the generated enum
code.

i965: Fix brw_finish_batch to grow the batchbuffer.

brw_finish_batch emits commands needed at the end of every batch buffer,
including any workarounds.  In the past, we freed up some "reserved"
batch space before calling it, so we would never have to flush during
it.  This was error prone and easy to screw up, so I deleted it a while
back in favor of growing the batch.

There were two problems:

1. We're in the middle of flushing, so brw->no_batch_wrap is guaranteed
   not to be set.  Using BEGIN_BATCH() to emit commands would cause a
   recursive flush rather than growing the buffer as intended.

2. We already recorded the throttling batch before growing, which
   replaces brw->batch.bo with a different (larger) buffer.  So growing
   would break throttling.

These are easily remedied by shuffling some code around and whacking
brw->no_batch_wrap in brw_finish_batch().  This also now includes the
final workarounds in the batch usage statistics.  Found by inspection.
